A gent at the range on sat had and SSR job on a 243, he had an issue with one that the internal thread broke away causing baffle strikes. I think he said this one was the replacement.
I didnt risk taking off the muffs as there were too many shooters, but all I could hear was a FFFFFFFfffffft! sound, he didnt stick around to chck it out more but it seemed pretty quiet.
Got a gunworks dualium on my 308 myself. they make them an inch? longer than when I got mine now I think.
